ELECTRIC SHAVER Hastings W. Baker, Great Neck, N. Y., assignor to General Theatres Equipment Corporation, New York, N. Y., a corporation of Delaware Application February 26, 1938, Serial No. 192,713

3 Claims.

The object of this invention is to improve the structure shown in the patent of Leonard M. Thorn and John M. Wall, No. 2,216,994, issued October 8, 1940.

I have shown my invention by way of illustrations in the following drawings in which;

Fig. -1 is a side elevational view thereof,

Fig. 2 is a perspective view of the cutting blade, and n Fig. 3 is a modification of the structure shown in Fig. 2.

The electric shaver consists of a body portion l in which is housed an electric motor which is provided with a drive shaft on which is mounted a wheel 2 which projects through the body portion and which can be twirled by the fingers of the user so as to start the motor. The body portion is provided with a guide 3 adapted to be laid against the fact of the user so as to correctly position the cutting blades and comb of a guard member 4. The motor shaft is provided with a pin adapted to be received within a bayonet slot 5 in a rotatable blade 6, thereby serving as a means to connect the rotary blade with the drive shaft of the motor. The rotary blade 6 is provided with bearings I and 8, and between the bearings 1 and 8 are spiral cutting blades 9. The whiskers can be guided into the cutting blades of the guard 4 and the spiral blades 9 will cut the whiskers by engaging the same between the said spiral blades and the straight edge blade ill of the guard member. The above reference characters do not correspond with the reference characters shown in said application for no attempt is made to describe all of the features embraced therein.

I propose to slit the bearing member 8, either by making one cut diametrically through the guard member 8 forming a slot II as shown in Fig. 2 or by making two slits at right angles to each other forming slots II and I2 as shown in Fig. 3.

In the said application, the bearing member 8 was not cut into sections and'therefore could not expand by centrifugal action. The result was that it had to be very closely machined which is in expensive process and, even after it was machined to extremely fine limits of precision,

it was found that in many cases the sleeve 8 was a little too small so that it did not allow as close a shave as would be the case if it hugged and closely fit the guard member 4. In numerous other cases it was found that the sleeve member 8 was a little too large so that it caused a binding effect which might even stop the motor,

or at least slow it down. By simply slitting the bearing member 8, or making it in sections with at least one of the spiral blades being connected to each of said sections, the rapid rotation of the rotary cutter would,. by centrifugal action, cause a snug fit between the various sections comprising the bearing 8 so that the spiral blades 9 would be brought into close contact with the inner periphery of the guard member 4 so as to give an exceedingly close shave. This eliminates the close precision work formerly required in machining the bearing member 8 because it no longer makes any difference whether the outer periphery of the guard member 8 is a little larger or a little smaller than the inner periphery of the contacting portion of the guard member 4.

I realize that changes might be made in the specific embodiment of the invention shown by way of illustration in this application. I wish to reserve to myself the right to make all changes which may verily fall within the scope of the J disclosure, except as I may limit myself in the following claims.

Having now described my invention, I claim: 1. A power operated razor comprising a body,

a hollow guard member carried thereby and provided with a slot and a rotary cutter having a plurality of blades rotatable within said guard member and adapted to engage the whiskers of the user against said slot to sever the same, end bearings at the outer end of and forming a part of said rotary cutter, said bearings being formed of a plurality of parts, each of which is radially movable by centrifugal action against the inner periphery of said guard member.

2. A power operated razor comprising a body,

a hollow guard member carried thereby and pro-- ing sleeves connected by spiral cutters rotatable in said guard, the bearing sleeve farthest removed from said handle being split radially, and each of the, parts thereof forming weights adapted to move outwardly by centrifugal action against the inner periphery of said guard, and a longitudinal slot in said guard through whicf whiskers may be cut by said cutters.
